The removable mattress topper includes a cover encapsulating the foam layer. The cover includes a top panel, a bottom panel, and sidewalls extending between the top and bottom panels, wherein the bottom panel comprises a zippered portion extending about at least a portion of a peripheral edge of the bottom panel. Also disclosed are mattress assemblies including the removable mattress topper, wherein the mattress assembly includes a mattress core and a cover encapsulating the mattress core, wherein the cover includes a top panel and a zippered portion about a peripheral edge of the top panel. The zippered portion of the mattress core is configured to mechanically engage the zippered portion of the removable mattress topper.

BACKGROUND

The present disclosure generally relates to mattress assemblies, and more particularly to removable mattress toppers including vibrating units.

Mattress assemblies including vibrating units for providing a massaging action to an end user are typically complex structures. For example, adjustable beds can include discrete powered massage elements built into the adjustable foundation upon which a mattress is disposed. Due to the spatial distance between the adjustable foundation and the mattress, the massage elements are dampened to such a degree that the massage elements often shake the bedding system in its entirety in order for the massaging action to be felt by the end user, which can disrupt sleep should the mattress be configured to accommodate more than one end user. Mattresses used in homes can also have massage motors built into the mattress portion of the bed. In each of these situations, when the massage mechanism becomes damaged, the entire complex structure must be serviced. The bed may be shipped back to the manufacturer for repair or a service technician may visit the user and remove or repair the massage mechanism. Standalone massage pads have been used in various cushioning structures such as chairs. However, because these pads vibrate and are not fastened to the underlying; structure, these types of apparatuses have a tendency to slide off the underlying surface. Moreover, these types of pads directly affect the intended comfort and breathability desired by the manufacture the mattress assembly.

Moreover, current vibrating mattress assemblies are unable to isolate the intended massage effect in order to target specific areas of the sleeper's body, due to the distance of the elements from the sleep surface (i.e., through an entire mattress). Instead, they are often configured to shake the whole bedding system, often disrupting a partner sleeping in the same bed.

Referring now to FIG. 1 , an exploded view of an exemplary mattress assembly 10 including a mattress core assembly generally designated by reference numeral 50 and a removable mattress topper including vibrating units generally designated by reference numeral 100 is shown in accordance with the present disclosure. FIG. 2 illustrates an exploded view of the removable mattress topper 100 by itself.

The removable topper layer 100 is dimensioned to overlay the mattress core assembly 10 in its entirety and be removably attached to the uppermost user-facing surface thereof. Typically, the mattress core assembly 50 and the removable mattress topper 100 are generally rectangular shaped as is generally shown. As such, the mattress assembly 10 including the mattress core 50 and the removable mattress topper 10 generally has a head end (H), a foot end (F) and lateral sides (S1), (S2) extending from the head end H to the foot end (F). However, it should be apparent that other shapes are contemplated to accommodate irregular shaped mattresses, e.g., custom mattresses such as circular beds or the like. In use, the removable mattress topper layer 100 is configured to be positioned between the mattress core assembly 50 and a bed sheet (not shown) that is positioned over the mattress core assembly 50 and the removable mattress topper 100.

The mattress core assembly 50 is not intended to be limited and generally includes one or more layers encapsulated within a cover. As shown in FIG. 1 , the exemplary mattress core assembly 50 includes a mattress core 52 that is encapsulated within a cover 56 overlaying the uppermost surface 58 and side surfaces 60 of the mattress core 52 that is fastened to a bottom panel 54, when assembled. As such, the cover 56 includes a top panel and sidewall panels extending about a periphery of the top panel. The top panel may be implemented as a padded upholstery layer with a quilted top that represents the actual sleeping surface. The bottom panel 54 is fastened to the sidewalls to encapsulate the mattress core assembly. The cover 56 and the bottom panel 54 can be sewn together or fastened using a zipper or the like.

The cover 56 further includes a zippered portion 62 about a perimeter of the top panel surface and is configured for mechanical engagement to a complementary zippered portion 114 on the removable mattress topper 100. The zippered portion 62 is at a peripheral edge of the cover and includes one or more strips of fabric, such as the fabric or fabrics employed as the upholstery material for the side panels of the cover. In one embodiment, the peripheral edge is secured, typically by stitching one edge of the fabric strip peripheral to the edge of the top cover panel. The opposite side of the fabric strip that forms the peripheral edge may include a zipper strip of the type that includes teeth that may be joined to an opposing zipper strip e.g., zippered portion 114 of the removable mattress topper 100.

The mattress core 52 can include one or more layers including, but not limited to foam layers, coil layers, air bladders, a side rail assembly extending about the sides of the mattress core, combinations thereof, and the like. The thicknesses of the various layers can vary and are generally from about ½ inch in thickness to about 14 inches or less in thickness, although greater thickness can be utilized. The uppermost layer 58 typically has a planar top surface adapted to substantially face the user resting on the mattress assembly and has length and width dimensions sufficient to support a reclining body of the user.

The coil layer, when present, generally includes coil springs that are not intended to be limited to any specific type or shape. The coil springs can be single stranded or multi-stranded, pocketed or not pocketed, asymmetric or symmetric, and the like. It will be appreciated that the pocketed coils may be manufactured in single pocket coils or strings of pocket coils, either of which may be suitably employed with the mattresses described herein. The attachment between coil springs may be any suitable attachment. For example, pocket coils are commonly attached to one another using hot-melt adhesive applied to abutting surfaces during construction.

Suitable foams for the different layers that include foam, include but are not limited to, polyurethane foams, latex foams including natural, blended and synthetic latex foams; polystyrene foams, polyethylene foams, polypropylene foam, polyether-polyurethane foams, and the like. Likewise, the foam can be selected to be viscoelastic or non-viscoelastic foams. Some viscoelastic materials are also temperature sensitive, thereby also enabling the foam layer to change hardness/firmness based in part upon the temperature of the supported part. Unless otherwise noted, any of these foams may be open celled or closed well or a hybrid structure of open cell and closed cell. Likewise, the foams can be reticulated, partially reticulated or non-reticulated foams. The term reticulation generally refers to removal of cell membranes to create an open cell structure that is open to air and moisture flow. Still further, the foams may be gel infused in some embodiments. The different layers can be formed of the same material configured with different properties or different materials.

The various foams suitable for use in the foam layer may be produced according to methods known to persons ordinarily skilled in the art. For example, polyurethane foams are typically prepared by reacting a polyol with a polyisocyanate ira the presence of a catalyst, a blowing agent, one or more foam stabilizers or surfactants and other foaming aids. The gas generated during polymerization causes foaming of the reaction mixture to form a cellular or foam structure. Latex foams are typically manufactured by the well-known Dunlap or Talalay processes. Manufacturing of the different foams are well within the skill of those in the art.

The different properties for each foam layer may include, but are not limited to, density, hardness, thickness, support factor, flex fatigue, air flow, various combinations thereof, and the like. Density is a measurement of the mass per unit volume and is commonly expressed in pounds per cubic foot. By way of example, the density of the each of the foam layers can vary. In some embodiments, the density decreases from the lower most individual layer to the uppermost layer. In other embodiments, the density increases. In still other embodiments, one or more of the foam layers can have a convoluted surface. The hardness properties of foam are also referred to as the indention load deflection (ILD) or indention force deflection (IFD) and is measured in accordance with ASTM D-3374. Like the density property, the hardness properties can be varied in a similar manner. Moreover, combinations of properties may be varied for each individual layer. The individual layers can also be of the same thickness or may have different thicknesses as may be desired to provide different tactile responses. Optionally, in some embodiments, one or more of the foam layers may be pre-stressed such as is disclosed in U.S. Pat. Pub. No. 2010/0072676, incorporated herein by reference in its entirety.

In other embodiments, the one or more layers overlying the foam layer including the vibrating units are coated with a phase change material (PCM), PCMs generally operate on the principle that a material requires a relatively significant amount of energy (heat) to change from a solid to a liquid and then back from a liquid to a solid. PCMs can therefore absorb large amounts of heat or energy from their environment and return large amounts of heat to their environment. This effective absorption, store and release of heat can be used to help regulate the temperature of an environment. The particular PCM is not intended to be limited and can be inorganic or organic. Suitable inorganic PCMs include salt hydrates made from natural salts with water. The Chemical composition of the salts is varied in the mixture to achieve required phase-change temperature. Special nucleating agents can be added to the mixture to minimize phase-change salt separation. Suitable organic PCMs include fatty acids; waxes (e.g., paraffins) or the like, which are generally known in the art.

Suitable air bladders can be self-inflating and/or inflatable using a pump or the like. Exemplary air bladders are disclosed in U.S. Pat. No. 10,357,114 and US Pat. Pub. No. 2019/174930 incorporated herein by reference in its entirety.

The mattress core assembly 50 can include other layers such as batting layers, fire retardant layers, waterproof liners, and so forth. In certain assemblies using coils, the one or more additional layers may include a relatively firm bottom panel layer that distributes the upward force of each spring top to provide a more uniform feel to the sleeping surface.

As shown more clearly in FIG. 2 , the removable mattress topper 100 includes a foam layer 102 including a plurality of vibrating units 104 embedded therein. Foam layer 102 can be a single foam layer or can be two foam layer 102 a and 102 b arranged in a side-by side relationship, with each foam layer 102 a and 102 b corresponding to different end users for those mattress assemblies dimensioned to accommodate two end users. That is, each of the foam layers 102 a and 102 b generally span about a length dimension intended for the mattress assembly and span about one half the width dimension. Foam layer 102 is not intended to be limited to any particular foam and generally includes recesses dimensioned to accommodate each one of the vibrating units at a specific location which are generally spaced apart and at locations corresponding to an end user's body position on the removable mattress topper 100. The vibrating units can be seated in the recesses or can be adhesively affixed thereto. An optional channel (not shown) can be provided in the foam layer 102 for the wiring of the vibrating units. Alternatively, the wiring can be provided on a surface of the foam layer 102

The vibrating units 104 are contained within housings and generally include a variable speed motor with a shaft and an eccentric cam attached to the shaft causing the motor to vibrate when in use. The frequency of the vibrations produced within the mattress topper may be controlled by varying the speed of each motor. The amplitude of the vibration may be controlled by re-positioning the eccentric weight. Operation of the individual vibrating units thusly imparts a resonating effect to the various locations about the mattress topper and to a person reclining upon the mattress topper. By varying the frequencies of the vibratory impulses and the level of resonance, a person may recline upon the mattress topper and mattress assembly for its comforting effects or, alternatively, be slowly lulled to sleep. A control module is provided to control operation of the vibrating units 104, which can include power regulation from a AC or DC voltage source, and is configured for communication to a wireless remote in a manner generally well-known in the art. The control module can be seated within a recess formed in the foam layer 102.

Foam layer 106 overlays the foam layer 102 including the vibrating units 104 and generally has a thickness sufficient to prevent the end user from sensing the physical presence of the vibrating units 104 and associated wiring when in the off position.

The removable topper layer 100 further includes a cover 108 defined by a top panel 110 and sidewalls 112 extending from the top panel 110. The sidewalls 110 are dimensioned to accommodate the combined thicknesses of layers 102, 104 and 106. A zippered portion 114 extends about a periphery of the sidewalls 110 and is engageable with zippered portion 62 of the mattress core assembly 50. The cover 108 include a bottom panel 116, which can be fixedly attached to the sidewalls 112 of the cover or removably fastened thereto. The cover and bottom panel fully encapsulate foam layer 102 including the vibrating units 104 and foam layer 106. The cover further includes at least one opening for a power cord.

Optionally, the removable mattress topper 100 can include additional foam layers (not shown) overlying and/or underlying foam layer 102 including the vibrating units 104.

The overall thickness of the removable mattress topper is generally from about 0.25 inches to about 6 inches. In one or more embodiments, the thickness of the removable mattress topper is from about 0.5 inches to about 3 inches in thickness, and in still one or more embodiments, the thickness of the removable mattress topper is from about 0.5 to about 2 inches in thickness.

Foam layer 500 includes two vibrating units 502 corresponding to a shoulder region of an end user, two vibrating units 504 corresponding to a back region of an end user, two vibrating units 506 corresponding to a lumbar region of an end user, and four vibrating units 508 corresponding to a leg and foot region of an end user. The vibrating units 502, 504, 506, and 508 in each respective region are generally connected in parallel to a control module 510 to permit independent activation with respect to each region as may be desired by the end user. The control module 510 is connected to a power supply 512. The control module 510 includes a wireless interface for connection to a control device accessible by the end user. In this manner, the end user can remotely select one or more different regions for a massaging action. In one or more embodiments, the control module communicates with a control device using any well-known or envisioned wireless communication technology, including, for example, Wi-Fi and Bluetooth™ wireless technologies. Exemplary control devices are not intended to be limited and include remote controls, phones, tablets, and the like that can be configured to wirelessly interact with the control module.

FIG. 6 schematically illustrates an exemplary mattress assembly including a removable mattress topper 600 as previously described including vibrating units at different zones for use with a mattress dimensioned for a single end user, e.g., a twin sized mattress. The different zones generally correspond to a shoulder zone 602, a back zone 604, a lumbar zone 606, and a leg and foot zone 608, which are in electrical communication with a control module including a wireless transceiver 610. A power source 612 provides power to the control module and vibrating units.
